Natural Factors Magnesium Oxide 250mg - 90 Caps

Natural Factors Magnesium Oxide

Magnesium is vital to hundreds of enzyme reactions and has more health benefits attributed to it than any other mineral including calcium. Magnesium, along with calcium, is a shock-absorber, helping to prevent the body from experiencing excessive stress.

Magnesium is an important electrolyte which helps the absorption of calcium, phosphorus, sodium and potassium. Magnesium is required for the B vitamins to work properly and is absolutely necessary for the utilization of thiamine.

Magnesium is necessary for growth and development, wound healing, immune system function, temperature regulation and many activities of the brain and nervous system. Shaky hands, nervousness, muscle spasms, irregular or rapid heartbeat, all respond favourably to magnesium.

Magnesium

Magnesium is an essential mineral for all known living organisms. Magnesium ions catalyze many chemical reactions in the human body, including those in the mitochondria where most of the energy inside each cell of the body is produced. It also plays a role in cell signalling within the body, with wound healing and with enzymes governing the replication of DNA.

Without magnesium, the transmission of nerve and muscle impulses is compromised. This can lead to nervous system disorders, muscle weakness or contraction, as well as cramps and spasms. For example, magnesium has been shown to decrease menstrual pain by relaxing the uterine muscles. Magnesium deficiency has also been strongly associated with depression, migraines, ADD, PMS, fibromyalgia, asthma, allergies and type II diabetes. Magnesium loss can be caused by some medications such as diuretics, antibiotics and some cell supporting drugs. Foods high in fat and oxalic acid interfere with the absorption of magnesium. Oxalic acid containing foods include almonds, chard, cocoa, rhubarb, spinach and black tea. Body requirements for magnesium increase with increased intake of zinc and vitamin D.

Who needs magnesium?

In short, most people...Recently, there has been some debate in regards to the efficacy of magnesium status testing using blood. It is argued that blood testing may not show deficiencies until they are dangerously low because only around 1% of the body's magnesium is found in the blood. It is possible that 50% or more of the population have low magnesium stores despite normal serum levels (a condition called "subclinically deficient"). These deficiencies may have to do with low dietary intake of magnesium, due to poor dietary habits, or loss through the refining and processing of foods. Chronic vomiting or diarrhea, excessive urination and sweating can also deplete magnesium. Foods rich in magnesium include dark leafy vegetables, bananas, avocado, peas, legumes, soy and whole grains.

Magnesium & Women's Health

In addition to decreasing menstrual cramping, as noted above, magnesium acts in pregnancy as a uterine relaxant that can prevent premature labour. Studies show supplemental magnesium in pregnancy also decreases the risk of birth defects such as cerebral palsy. It has also been researched for its ability to protect against osteoporosis as well as supporting optimal cell growth.

Magnesium and Cardiovascular Health

Given its vital role in nerve and muscle function, magnesium is also an especially important mineral for heart health. Deficiency can cause abnormal heart rhythms, coronary spasms and calcification of the arteries. Studies have also shown that diets high in magnesium significantly reduce the risk of high blood pressure, and this correlation is stronger in women than in men.

Magnesium and Type II Diabetes

Excessive urination is one of the signs of poorly controlled diabetes. Because magnesium is lost in the urine, many diabetics are deficient. Research has been shown that magnesium may be protective against getting Type II Diabetes, and that supplementation may improve blood sugar control in those already affected.

Magnesium as a Laxative and Detoxifier

Because of its high osmotic gradient, taking large doses of magnesium can lead to increased water content in the intestines. This results in a "flushing" of the intestinal contents that is often used to treat constipation or to promote cleansing for detoxification. Magnesium hydroxide (milk of magnesia) is the most commonly used form of magnesium for treating constipation. For detoxification, commercial products containing magnesium sulfate (Epsom salt), and magnesium citrate are used. It is important never to attempt to create your own detoxification products using the above ingredients as fluid balance is delicate and misuse can result in severe dehydration. Consult your healthcare practitioner before beginning any detoxification protocol.

Types of Magnesium Which to choose?

There are many different forms of magnesium available on the market, making choosing one difficult. Each type is different in the cost and the amount available for absorption. It is difficult for researchers to narrow down which is the best form due to the short half-life of magnesium in the body and difficulties with variations between testing methods. Here are some widely accepted facts:

The least bioavailable forms are magnesium oxide, bicarbonate and carbonate. Because they are less soluble, they are also more likely to cause intestinal side effects such as discomfort and loose stools. The magnesium in antacids is also not a good supplemental source because it neutralizes stomach acid and will impair the absorption of other minerals, like calcium.

Magnesium as an amino acid chelate, such as magnesium glycinate or magnesium taurate, is up to 4 times better absorbed than magnesium oxide and can be taken with our without food. Also, magnesium taurate has added benefit for the heart, so you may want to consider this form if you are supplementing for cardiovascular benefits. Magnesium chloride, magnesium citrate, and other magnesium salts are about 30% bioavailable. Magnesium glycinate and citrate are both soluble forms, considered highly absorbable that provide a high elemental mineral content. These are probably the most widely recommended forms.

Additional Information

Children:Suitable for children at the level of the Recommended Dietary
Allowance:

Infants: 0-0.5 year 40 mg, 0.5-1 year 60 mg
Children: 1-3 years 80 mg, 4-6 years 120 mg, 7-10 years 170 mg

Pregnancy and Nursing: Considered safe during pregnancy and lactation at the Recommended Dietary Allowance level of 350 mg daily.

Seniors: Elderly persons who take many magnesium-containing laxatives and antacids may develop toxicity symptoms.

Contraindications

There are many drugs that appear to adversely affect magnesium status. Most notable are many diuretics, insulin, and digitalis.
A high calcium intake and a high intake of dairy foods fortified with vitamin D results in decreased magnesium absorption.
If you suffer from a serious kidney disorder or are on hemodialysis, do not take magnesium supplements unless directed by a health care practitioner.
People with severe heart disease (such as high-grade atrioventricular block) should not take magnesium (or potassium) unless directed by a health care practitioner.
